Nigroporus was defined by William Alphonso Murrill in 1905 (Murrill 1905). This genus is found throughout the tropics (Hattori & See 2003). The Ancient Greek term πόρoς (“pore”) and the Latin word niger (“black”) are combined to form the genus name (Donk 1960). Nigroporus is characterized by its annual or perennial fruit bodies. They can be pileate (capped) or crust-like. If a cap is present, it can be a smooth, concentric zone, or scrupose (rough with tiny hard points) (Kuo 2018). The hue ranged from pink to violet, to vinaceous-brown and greyish-blue. The color of the pore surface matches that of the cap; the pores are typically round and angular in shape and size. Vinaceous brown to pink and purple are the context (Kuo 2018). Nigroporus causes white rot in wood (Adarsh et al. 2015). The phylogeny of Nigroporus was studied using ITS and LSU sequences data and was found that Nigroporus was closely related to the Tramates based on DNA sequences (Xu et al. 2020). Nigroporus has seven epithets listed in the Species Fungorum (2024).
